AR MAGLOCK Gen 4 Äâ‚¬â€œ AR-15 (.223 / 5.56) Fixed Magazine Lock and Release Solution (AR MAGLOCK in anodized black components, KingPin in black).
The Gen 4 and KingPin combo allows for minimal separation (action disassembly) of the upper and lower receivers. The new KingPin holds the upper receiver from flying open when disassembling the action.
Just a simple push on the pin with your thumb opens the action for mag changes, then automatically re-locks when you push the receivers together.
The Gen 4 benefits:
Äâ‚¬â€œ New set screw on locking arm, allowing for adjustment to ANY receiver width including billet, composite, or 80% non mil-spec receivers.
Äâ‚¬â€œ Allows for Äâ‚¬ï¿½free stateÄâ‚¬Â¯ adjustment when traveling outside California. Just reset the set screw to the end of the post and the locking arm will work just like an OEM magazine release button.
The KingPin benefits:
Äâ‚¬â€œ Retain your critically important bolt catch
Äâ‚¬â€œ Seamless double feed clearing
Äâ‚¬â€œ Bolt hold back on last round
Äâ‚¬â€œ Fast magazine changes (as fast as OEM mag release button)
Äâ‚¬â€œ Clear access to your safety selector
Äâ‚¬â€œ Easy removal from the receiver to fully open the action
